Revision 56--Updated Online 09/30/20 NAPS UFSAR 2 Revision 56Updated Online 09/30/20 Changes Made under the provisions of 10 CFR 50.59 except Section where indicated in brackets.
Section 1.2.1 0, Figure 9.5-1, Section 9.5.1.1 Section 1.2.1 0. This section was updated to
[NAPS-UCR-2018-009] add Clean Agent onto the list of fire suppression systems used at the station.
Figure 9.5-1 The PBX Building was added to this figure and it was shaded to denote that it is protected by a Clean Agent system.
The Legend was also updated.
Section 9.5.1.1 lists the Miscellaneous Areas around the plant that are sections [that] do not require a fire suppression system but rely on building location to protect safety-related systems and equipment. The PBX Building will be added to this list.
Section 8.3.1.1.1 Section 8.3.1.1.1: changes one of the two sets
[NAPS-UCR-2015-022] of normal buses connected to the reserve station service transformers from 5-inch pipe bus to 6-inch pipe bus.
Section 7.3.1.3.5, 7.3.1.3.5.3, Table 7.3-2, Changes:
Figure 7.3-1, Figure 7.3-5, Figure 7.3-6, Open Phase Condition Project Section 8.3.1.1 NA-15-00061, NA-15-00062, NA-15-00063,

Revision 56--Updated Online 09/30/20 NAPS UFSAR 3 Revision 55Updated Online 09/30/19 Changes Made under the provisions of 10 CFR 50.59 except Section where indicated in brackets.
UFSAR 9.3.3 Vent and Drain System / 9.3.3.2 The change clarifies the discussion of fire System Description protection water piping within those areas
[NAPS-UCR-2019-004] containing sump pumps described in UFSAR 9.3.3 Vent and Drain System. The existing description would indicate that no fire protection water system piping is installed in the Reactor Containments, Chiller Rooms, and Emergency Switchgear Rooms where the described sump pumps are located. For these areas, normally dry fire protection water system piping is located in the area. The change provides this clarification.
15.2.1.2.1 and 15.2.1.2.2, Figures: 15.2-1 The FSAR description of the Rod Withdrawal through 15.2-5,Tables: 15.1-2 and 15.2-1 from Subcritical (RWSC) accident analysis
[NAPS-UCR-2019-005] has been updated based on ETE-NAF-2019-0079. The changes include the following:
- Updated text for current core thermal/hydraulics code.
- Deleted reference to legacy fuel types.
- Updated figures and table to reflect RWSC analysis of record plots and new Doppler model input, respectively.
Revision 56--Updated Online 09/30/20 NAPS UFSAR 4 Revision 55Updated Online 09/30/19 (continued)
Changes Made under the provisions of 10 CFR 50.59 except Section where indicated in brackets.
Appendix 3A Compliance with Safety Guides Surveillance Test Interval Evaluation Section 3A.45 STI-N12-2017-003 has evaluated and
[NAPS-UCR-2018-010] approved a change in the 31 day surveillance testing of the Station Emergency Diesel Generators to a 92 day frequency (or quarterly). Based on review of historical emergency diesel generator testing and overall reliability of the Station diesel generators, adjustment of the 31 day surveillance test to a quarterly (92 day) test frequency is considered acceptable. Implementation of a quarterly test frequency will require a standard pre-lube and air roll of the diesel generator to be performed on a 45 day frequency. This will ensure adequate oil lubrication is maintained on the engine internal components reducing the potential for mechanical wear supporting long term reliability. The surveillance requirement for demonstrating the OPERABILITY of the EDGs are in accordance with the recommendations of Safety Guide 9, Regulatory Guide 1.108, (subsequently replaced by Regulatory Guide 1.9), and Regulatory Guide 1. 137, as addressed in the UFSAR. An exception to Regulatory Guide 1.9, Revision 3, Section C.2.3.2. 1 will be implemented under STI-N12-2017-003.

Section 9.2.2.3.1, Table 9.2-8, Table 9.2-9, DC NA-17-00152 restores the ability of Figure 9.2-2 1-CC-LCV-100 to function without
[NAPS-UCR-2017-015] generating water hammer in the CC Surge Tank makeup line and installs manual valve controls in the MCR. It also transfers the primary responsibility of CC Surge Tank makeup from CN to PG, while retaining CN as a backup source via a separate, newly installed makeup line leading to the CC Surge Tank.
UFSAR Table 3.2-1 Per corrective action assignment CA3063277,
[NAPS-UCR-2018-004] the change corrects Table 3.2-1 to be consistent with Section 9.3 and other licensing basis information that the boric acid tanks and delivery system (pumps, piping, blender, etc.)
to the reactor coolant system are required to be tornado missile protected.
Section 10.2 ETE-NA-2018-0050 provides the technical
[NAPS-UCR-2018-013] justification for test frequency revision of 1/2-PT-34.6 specified in UFSAR 10.2. 1/2/-PT-34.6 (Turbine Generator Motor Driven Oil Pumps) is being revised to a "SHALL" NEIL test frequency of quarterly instead of monthly ("SHOULD"). No insurance penalty applies for said change. The updated UFSAR will specify a frequency "established by the Loss Control Program",
which provides flexibility for future test frequency revisions.

[NAPS-UCR-2018-001] weight % U-235 to 5.0 weight % U-235; revises allowed storage patterns and initial enrichment/burnup/cooling time requirements for fuel assembly storage in the spent fuel pool in order to meet keff requirements under normal and accident conditions (both Region 1 and 2 storage); permits the storage of any fuel assembly containing a full length Rod Cluster Control Assembly in Region 2 without regard to the new burnup curves. The LBDCR used updated methods for the criticality analyses. These methods were also used to update the criticality analyses for the New Fuel Storage Area (NFSA). However, there are no changes to fuel storage requirements in the NFSA other than the increased enrichment.

Revision 56--Updated Online 09/30/20 NAPS UFSAR 1 FOREWORD In the May 9, 1980, edition of the Federal Register (45 FR 30614), the NRC published a Final Rule requiring all licensed reactors to periodically update their Final Safety Analysis Reports. The purpose of the Rule was to establish baseline reference documents to be used in recurring safety analyses by licensees, the NRC, or other interested parties.
The Supplementary Information section of the Final Rule notice stated that submittal of an updated FSAR does not constitute a licensing action, but is only intended to provide information. The NRC Staff may review the material submitted, but does not intend to formally approve it. The NRC intends to use the updated FSAR in the future for appropriate applications such as reporting of deviations from conditions stated in the UFSAR.
The Rule became effective July 22, 1980, and established the following basic requirements for VEPCOs nuclear power stations:
- The UFSAR was to reflect information and analyses submitted to the NRC by VEPCO, or prepared by VEPCO pursuant to NRC requirements, since submission of the original FSAR (or, as appropriate, the last UFSAR).
Note: The Supplementary Information section of the Final Rule notice clarifies this requirement by stating that no analyses other than those already prepared or submitted pursuant to NRC requirements are required because of the Rule: however, FSAR analyses that are known to be nonconservative based on new analyses must be updated. Other new analyses not previously included in the FSAR may be incorporated in the UFSAR at the option of the licensee. Furthermore, specialized studies provided in the original FSAR (e.g., seismology, meteorology) should include the latest information developed in response to NRC requirements when these studies are transferred to the UFSAR, and program type material referenced by the UFSAR (e.g., security plan, emergency plan, QA Program) should be referenced accurately. In addition, the level of detail in the UFSAR should be at least the same as but not necessarily greater than that provided in the original FSAR. Information on design changes should not be included until the changes are approved for use and operable.
- The initial UFSAR was due no later than July 22, 1982.
- The initial UFSAR was required to be up-to-date as of a maximum of six months prior to the date of filing (January 31, 1982, was chosen by VEPCO as the cutoff date).
- Subsequent updates are required at least annually and must reflect changes made up to a maximum of six months prior to the date of filing.
Revision 56--Updated Online 09/30/20 NAPS UFSAR 2
- One original and 12 copies of the initial UFSAR and subsequent updates are required to be submitted to the NRC.
- The updates are required to be certified by a duly authorized officer of VEPCO.
- The initial UFSAR should be a clean document without change bars and revision numbers. The subsequent annual revisions should include change indicators and page change identification.
In response to the foregoing FSAR update requirements, VEPCO and NUS Corporation executed an Agreement for FSAR update services in April 1981, and NUS began work on the project immediately. The project was accomplished in four basic phases:
- 1. Document Retrieval
- 2. Change Package Development
- 3. FSAR Revision
- 4. Printing
- During the initial document retrieval phase in the Spring of 1981, NUS engineers researched the licensing correspondence files at VEPCO offices in Richmond and the design change files at the plant sites. All documents potentially affecting the FSAR were copied and taken to the NUS home office.
Following the initial document review phase, NUS engineers periodically visited Richmond and the plant sites to acquire newly developed information. NUS was also placed on the distribution list for VEPCO/NRC correspondence.
The document retrieval phase continued until early 1982, at which time sufficient information was available to document changes up to the January 31, 1982, cutoff date.
- The documentation retrieved during the first phase was reviewed in detail during the second phase to determine the particular two-digit section or sections of the FSAR that should be revised, i.e., 1.1, 1.2, 1.3, etc. Copies of the document (or of the particular pages of the document that were of interest) were placed in separate files corresponding to the two-digit sections. These files were defined as change packages. Development of the change packages continued in parallel with the document retrieval phase, with new information being reviewed and assigned to appropriate change packages. The final change packages became a work product delivered to VEPCO on conclusion of the update effort and are available for tracing the sources of changes to the original FSARs.
- After development of the initial change packages the material filed therein was used in the third phase of the project to make the actual FSAR revisions. The revision process continued in parallel with the continuing development of the change packages.
Revision 56--Updated Online 09/30/20 NAPS UFSAR 3 The revision phase for most FSAR chapters included two cycles of VEPCO review and comment. These comments became part of the change packages and were used in the development of the final draft UFSAR.
- VEPCO reviewed and approved the final draft chapters of the UFSARs for printing. The printer prepared approximately 125 sets of the UFSARs. NUS delivered one original and 12 copies of the UFSAR directly to the NRC on July 20, 1982, for Surry and July 22, 1982, for North Anna. The original UFSARs were transmitted under cover letter supplied to NUS by VEPCO (see the attachment to this foreword). The remaining copies were shipped to Richmond and the plant sites.
The following work products were also delivered to VEPCO by NUS and are available for use in producing subsequent annual updates:
- Printers copy of the UFSARs
- Annotated FSARs (2 copies)
- Final Change Packages (2 sets)
- Plant Drawing Indexes
- Key Word Indexes
- Update Procedures
- Introductory Volumes to the FSARs including this foreword, a list of effective pages, the key word indexes, the plant drawing indexes and a record of changes.
Further 10 CFR 50.71(e) rulemaking pertaining to UFSAR requirements for nuclear power stations was promulgated as recently as July 29, 1996 [61 FR 39278]. In particular, the annual revision requirement has been relaxed to six months after each refueling outage provided the interval between successive updates does not exceed 24 months.
The NRC issued a letter to licensees dated October 9, 1996, entitled Request for Information Pursuant to 10 CFR 50.54(f) Regarding Adequacy and Availability of Design Basis Information. The letter required submittal of information that will provide the NRC added confidence and assurance that Virginia Electric and Power Companys nuclear plants are operated and maintained within their design bases and that any deviations are reconciled in a timely manner. The Companys response (Serial No.96-535) dated February 7, 1997, described previously conducted programmatic reviews of the Updated Final Safety Analysis Report (UFSAR). The 1996 UFSAR Project Team examined the existing administrative controls for maintaining UFSAR content and usability. Process enhancements to simplify administrative
Revision 56--Updated Online 09/30/20 NAPS UFSAR 4 controls, to increase accountability for technical content, and to improve UFSAR accessibility and usability are promoted by conversion to electronic media.
Under separate cover (Serial No.97-108) dated May 23, 1997, Virginia Electric and Power Company notified the NRC about its project to address potential regulatory concerns involving the current design and licensing bases for the Surry and North Anna Power Stations. This project scope exceeds the level of scrutiny normally applied to the current licensing basis through routine surveillance and quality assurance activities. In order to facilitate thorough review, exhaustive validation, and a rigorous corrective action process, the recommended conversion to electronic media was implemented in Revision 32 of the North Anna UFSAR. The entire text of the UFSAR was entered into electronic media. The conversion was accomplished by a process of augmenting recent UFSAR revision word processing packages with scanned-in optical character recognition documents for the balance of text, tables, and figures not previously stored electronically. A 100-percent word-for-word proofing was conducted by comparing a printed version of the entire electronic document with current controlled distribution copies. Thus, the electronic UFSAR was conveyed into service as the quality assurance document of record without introducing any substantive, technical, or non-editorial changes.
